Boost Gauge Reading

I just replaced all the vacuum lines on my Z. I started her up and the boost gauge is kicking all the way past 7 and staying there at idle. Any ideas on a possible problem? Any help is appreciated.

Thanks for the response. I have another question. Does the 83 turbo have hydrolic lifters or non-hydrolic?

Check the head casting... it should say P90, or P90A right by sparkplug#1. Most P90A's are hydraulic.

Just checked and it's a P90 A, so I will assume hydrolic. I seem to have a slight tick when I first start it up over #6 cylinder. I might have a weak lifter.

On another note is there a way to check the boost sensor to see if it's still good? Oh, and thanks for the help so far.

figured out the boost issue. it was plugged in to the wrong connector. And also pulled the valve cover and checked. Looks like I might have a weak lifter. I'll just run a heavier weight oil for now. Thanks for your help Nismopick.

Found some info on disassembly and cleaning of the hydraulic lifters. Followed the instructions and now no ticking, purrs like a kitten.

where'd you find this info? I'd like to know as I have a P90A or is it in the Haynes guide?

duowing the info is on another forum, but here is the link It really helped me out.

On a side note, has anyone had any experience with running some engine flush through the system prior to oil change? I was thinking of doing this, but was concerned with damaging the engine.

Run some ATF through the motor. I add some, drive it around the block a couple times, let it cool, then drain it.
